ALBERT KIRKS, OF CANTON, OHIO, ASSIGNOR TO THE DIEBOLD SAFE AND LOOK COMPANY, OF SAME PLACE.

OPERATING MECHANISM FOR DOORS OF SAFES AND VAULTS.

SPECIFICATION forming part of Letters Patent No. 384,2$2, dated June 12, 1888.

Application filed October 14, 1887. Serial No. 352,334. (X model.)

To all whom, it 12mg concern:

Be it known that 1. ALBERT KIRKS, a citizen of the United States, and a resident of Canton, county of Stark, State of Ohio, have invented a new and useful Improvement in Operating Mechanism for Doors of Safes and Vaults, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of IO this specification.

My invention relates to improvements in operating mechanism for the doors of safes and vaults; and it consists in certain features of construction and combination of parts, as

will be hereinafter set forth in the claims.

Figure 1 is an isometrical view of the safe front and door, illustrating one form of my invention as applied thereto. Fig. 2 is same view of safe front and door, illustrating another form of application of my improvement. Fig. 3 is a transverse sectional view of Fig. 1. Fig. 4 is a view in perspective comprising parts shown in Fig. 2 detached. Fig. 5is aview in perspective comprising parts shown in Fig. 1 detached;

Similar letters of reference indicate corresponding parts in all the figures of the accompanying drawings.

As my invention is applicable to many of 3c the well-known forms of safe and vault doors,

- as well as differcntplans of hanging such doors, I will, forthe purpose of this application, proceed to describe my invention, referring to the safe and other parts only as conjunctional 5 thereto.

Letter A represents a safe-frame, and B a safedoor, the outer edge of which is provided with offsets a, tongues b, and grooves c. The door-jamb G has similar offsets, d, grooves e, o and tongucsf. In the grooves c and 6 there is placed a suitable packing, against which the tongues b and f are pressed when the said tongue enters the grooves c and e.

To carry thedoor vertically into the jamb,

the tongues b and f, parallel with and entering the grooves a and 0, there is provided a swinging frame or crane, D, formed'in this case of the hinged parallel bars E and a vertical strut, F. The ends h of the bars E have a pivotal connection with the body or frame of the safe, and to the free ends it of said bars the door B is pivotally secured.

To force the door into locking position, one or more presser-shafts, G, Fig. 1, G, Fig. 2, are provided, supported in journal-boxes H and 5 H. On the ends of said shafts there is provided an outwardly-projected pin, m,(see Fig.

5,) which is eccentric to a line drawn through said shaft.

To the front of the safe frame there are secured outwardly-projected abutments J, hav: ing on their in uerside face a rightangle groove or camway, 11, adapted to receive the eccentriepin m'when the door is closed. On the shaft G, Fig. 1, there is mounted a worm-wheel, K, that engages a worm, L, mounted on a crossshaft, M, said shaft supported by and rotated in a journalhox, p, integral with thejournalbox H, and asuitable end support in the door.

On the outer end of said shaft M is mounted a cranlewhecl, N, or other form of handle crank, as g, by which the said shaft may be rotated.

The operation is as follows: When the door is swung into the jambs, the pins or, resting 7 above the center line of the shaft G, pass into the opening a, and by turning the crank N, rotating the shaft M, and the worm L, engag iug-wornrwheel K, the shaft G will be rotated, turning the pins m down into the groove on and 8 agaiust'the abuttingside 1' of groove,whereby the door will be forced into its proper position, the tongues c andf resting against the packing in the grooves c and b, forming an air and gas tight joint, and at the same time bring the 3 locking-bolts into register with the perforations provided therefor in the door-jambs. By a reverse movement of the crank the door may be drawn out and swung open. By this arrangement a compact and powerful means for go closing and opening the door against the atmospheric pressure, both within and without the safe, is secured,

In Fig. 2 is shown one method of applying my invention to large safe or vault doors, and consists in providing two presser-shafts, G, supported in journal-boxes, as H, provided with outwardly -projected arms 0, secured thereto, said arms having at their outer ends a pivotal connection, as s, with a link, P, by which the two shafts Gare connected through the arms O. To operate said link for the purpose of rotating the presser-shafts G, a journatbox and hanger, Q, is provided, as shown, in which a crankshaft, R, is supported, the crank having a pivotal connection, as u, with the link P, that in movement will coincide with the pivotal connection of the said link to the arms 0. On the free end of the crank-shaft B there is mounted a worm-wheel, S, which engages with a companion wheel, T, mounted on the shaft U, which is supported in the V hanger ,t and a suitable end support resting on the door. On the outer end of the shaft U there is mounted an operating crank, V, hav ing ahandle,VV, by which the shaft and wormwheels T and S may be rotated, whereby the link P maybe vibrated and the shaft G rotated, as and for the purpose hereinbefore stated in describing the parts comprised in Figs. 1 and 5; or, if preferred, other forms of cams, abutments, and eccentrics may be used, such as shown in Figs. 2 and 4, in which a stationary pin, 1), is supported by hanger w, and on the end of the shaft Gan eccentric end aperture or cam, 00, open on one side, as y, through which the abuttingpin may be passed into engagement with the eccentric portion of the aperture, by which the door may be forced into locking position.

Having thus fully described the nature and object of myinvention,what Iclaim,and desire to secure by Letters Patent, is

1. The combination, with the door-frame and the door hinged thereto and capable of a tilting movement on its own pivotal connection independent of its swinging movement on its hinge connection with the door-frame, of a rotary presser-shaft, a worm-wheel and worm for rotating said shaft, and eccentric mechanism connected with the shaft and frame,whereby the rotary movement of the shaft will cause the door to move bodily toward and away from its seat in theframe, substantially as set forth.

2. The combination, with the door frame and the door hinged thereto, of presser-shafts having lugs or arms projected laterally therefrom, a link connecting the projecting arms, a wormwhee1 having a crank-connection with the link, and a worm in engagement with the worm-wheel and provided with an operatingcrank whereby the presser-shafts are simultaneously rotated, substantially as set forth.

3. The combination, with the door-frame and the door hinged thereto, of a pressershaft having an eccentric aperture or groove in the end thereof, open at one side, a stationary pin adapted to engage the said eccentric groove, and means for rotating the pressershaft, substantially as set forth.

In testimony whereof Ihavehereuntoset my hand this th day of October, A. D. 1887.

ALBERT KIRKS.
